Chrysanthemum plant named ‘Power Yellow’

ABSTRACT

A new cultivar of  Chrysanthemum , ‘Power Yellow’, characterized by it&#39;s early and free flowering habit, its daisy-type inflorescences with yellow ray florets and bright yellow disk florets, its vigorous freely branched growth habit, its small leaved dark green foliage and its uniform, rounded and outward spreading plant habit.

Botanical classification: Dendranthemum×grandiflora.

Variety denomination: ‘Power Yellow’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Dendranthemum×grandiflora ‘Power Yellow’ (syn. Chrysanthemum×morifolium) and hereinafter by its cultivar name, ‘Power Yellow’.

The new Chrysanthemum ‘Power Yellow’ was discovered as a naturally occurring whole plant mutation of the Chrysanthemum cultivar ‘Apricot Cherie’ (U.S. Plant Pat. No. 12,961). The new Chrysanthemum was selected as unique by the inventor as a single flowering plant within a population of the parent variety in March 2005 in Niagara on the Lake, Ontario, Canada.

In comparison to the parent plant, ‘Apricot Cherie’, ‘Power Yellow’ has yellow-colored ray florets whereas ‘Apricot Cherie’ has tan colored ray florets. ‘Power Yellow’ has similar characteristics to the parent in growth habit and flowering response, which distinguishes itself from other cultivars of Chrysanthemum with yellow colored ray florets. In comparison to the cultivar, ‘Yellow Cherie’ (U.S. Plant Pat. No. 9,713), ‘Power Yellow’ differs in having a larger plant size, yellow ray florets that are deeper in color, and a different blooming time. ‘Power Yellow’ begins to bloom about one week later than ‘Yellow Cherie’.

Asexual reproduction of the new cultivar was first accomplished via stem cuttings in March 2005 in Niagara on the Lake, Ontario, Canada. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar of Chrysanthemum. These attributes in combination distinguish by ‘Power Yellow’ as unique from all other varieties of Chrysanthemums known to the inventor.

-   -   1. ‘Power Yellow’ is early flowering with daisy-type         inflorescences about 4.5 cm in diameter.     -   2. The inflorescences of ‘Power Yellow’ have yellow ray florets         with bright yellow disk florets that open from bronze colored         buds.     -   3. ‘Power Yellow’ has a freely branched, uniform, rounded and         outward plant habit.     -   4. ‘Power Yellow’ has a uniform flowering response.     -   5. ‘Power Yellow’ has small leaved dark green foliage.     -   6. ‘Power Yellow’ is a vigorous grower.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Chrysanthemum, ‘Yellow Power’. The photographs were taken of a plant grown in a 5-inch pan pot planted with 3 rooted cuttings and grown under greenhouse conditions for 10 weeks.

FIG. 1 is a photograph that provides a side perspective view of a typical plant in bloom when grown as a spray-type.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘Power Yellow’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Chrysanthemum.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of plants of the new cultivar as grown in a 5-inch pan pot planted with 3 pinched rooted cuttings and grown under greenhouse conditions at an average temperature of 65° F. for 10 weeks. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
